I live in Louisiana, and have a new tree, which seems to have been invaded by a swarm of unknown bugs. There are several different types of bugs, some dark, some almost clear They are eating the leaves, and I was wondering if someone could PLEASE identify and suggest the most effective method of removal!!!! I've tried an insecticide several times, with no success! Thanks in advance!!!!
they're probably aphids or thrips...there are a few different types and the aphids can change appearance a bit as they mature. what kind of tree is it? (i'm not familiar with those leaves) what treatments have you already tried?
They look like Aphids to me. Aphids can be different colors from transparent green to a dark grayish black and different sizes too. They can also be difficult to control. Most products used for aphids are contact insecticides. This means that the aphids must be hit directly with spray. Aphids tend to hang out on the lower surfaces of leaves so you need to make sure you thoroughly wet those areas when you spray. Insecticidal soaps are very good against aphids. They also require direct contact with the insects and leave no residual effect. With all insecticides it is important to follow the directions for re-application. If it says to spray again after 7 days make sure you do it as this will kill any critters that slipped through the first time. If you want to try the natural approach, Lady Bugs love to dine on Aphids. You can buy them at many garden centers or nursery's. Best of luck!
Aphids! As Wild-Rose says, insecticidal soaps are the way to go. I have had great success with a brand called Safer's, which, in Canada at least, can be found in the garden section of big-box stores like WalMart and Home Depot. The other thing to look at is how they may have gotten onto your tree. It looks like an Apple or a Plum; this makes it quite likely the aphids were at least initially placed on the tree by ants. I'd take the precautionary step of putting a Tanglefoot ring on the trunk to prevent further ant invasion and possible reinfection with the aphids.
Thank you all! Will have to look into suggested products! As far as tree species...I'm not really sure, but plum or apple seem possible, got is on clearance with no id tag!! Thanks!
